Purpose The learning from action (LfA) workshop was born more than 20 years ago and held in various places in Italy. This study aims to provide a learning experience for therapeutic communities (TCs) workers. During these years, the LfA work has developed by creating a dialogue between the experiential conferences and the group relations conferences (GRC) run by the Tavistock Institute. In this paper, the author explores the dialogue between (the leadership-oriented) GRC and (democratic) TC culture. Design/methodology/approach The authors intend to show how this dialogue has developed in LfA, describing tasks, purposes and critical aspects of LfA specific events: decision-making plenary, decision-making, TCs, action, dialog between cultures, GRC, learning methodology, decision-making group, activity group, morning and evening community meetings. Findings The authors confirmed the idea that acting and working together is a way of learning and communicating with each other. The role activities and works the authors do together to provide for the community in LfA have a more authentic quality of life than the purely verbal reflective work of a GRC. Originality/value The paper describes how LfA has developed and consolidated over the years, constituting an original learning model inspired by the typical activities of the culture of democratic TCs and the learning methodology of GRCs.

A survey of the most prominent definitions of zombie firms, together with their replication on a common dataset for euro area firms spanning the years 2004-2019, shows limited overlap and low comparability in the sets of firms identified by several prominent studies. Such low comparability raises the concern that these definitions are less capturing true zombie firms but rather financially vulnerable ones, and that the policy discourse may be misguided by statements on effectively distinct groups of firms. Thus, a formalization of the classifications of zombie firms is introduced which helps to make order in the growing number of variations and identification methodologies. Such formalization allows the concept of binary identification to be extended to that of fuzzy zombie identification, which allows quantification of a certain degree of \"zombieness\". A general procedure to turn arbitrary binary classifications into fuzzy ones is also presented and is shown to successfully increase consistency between zombie definitions.

Purpose Many people in severe mentally disturbed states do not use language or other symbolic media well or coherently. Therefore, the non-verbal medium needs to be understood by workers with such people. The “Learning from Action” experiential workshop was developed in order to provide an opportunity to learn about hidden messages in the relationships and roles occurring in activities. In August 2017, a workshop was run for the first time in Japan. The purpose of this paper is to report the experience and dynamics observed by the three consultants, who are here the authors of this paper. Design/methodology/approach After the workshop all the staff and members, including interpreters, were invited to give feedback. Findings Analysis of the feedback data showed certain important dynamics, concerning especially dependence, cultural defences and the defensive role of activity in a multicultural context. Research limitations/implications This is an initial experience to be followed up by later feedback and further workshops. Practical implications Workers awareness of non-verbal communication within the roles of work activities is a training possibility. It faces various resistances including the mental health assumptions of meaninglessness of any communication outside the verbal. Originality/value This is a method of training not widely used even in European countries, and is the first in a country in the far east.

This thesis is mostly based on the research presented in [1, 2, 3]. We introduce a novel efficient framework to treat infinite periodic vortex lattices in rotating superfluids under a mean-field Gross-Pitaevskii description. In doing so, we introduce a generalisation of the Fourier transform which correctly diagonalises the kinetic energy terms while respecting the required twisted boundary conditions. We call this integral transform a Magnetic Fourier transform. Testing the method, we re-obtain known results in the lowest-Landau-level regime, and further extend to stronger interacting regimes. We provide an extension of the above method to treat multicomponent systems, demonstrating that new degrees of freedom need to be introduced for each new component. We then employ this method to investigate the ground states of binary superfluid systems whose constituents have equal masses, thereby extending previous work carried out in the lowest-Landau-level limit to arbitrary interactions within Gross-Pitaevskii theory. In particular, we find that the interactions depauperate the phase diagram, with only the triangular lattice phase surviving in the limit of strong interactions. Withal we prove this applies regardless of the mass ratio of the constituents. We further investigate binary superfluid systems with non unitary mass ratios, obtaining a range of novel and exotic vortex lattice configurations. Finally we derive a linear relation which accurately describes the phase boundaries in the strong interaction regime.

We investigate a mixture of two repulsively interacting superfluids with different constituent particle masses: \\(m_1\\ne m_2\\). Solutions to the Gross-Pitaevskii equation for homogeneous infinite vortex lattices predict the existence of rich vortex lattice configurations, a number of which correspond to Platonic and Archimedean planar tilings. Some notable geometries include the snub-square, honeycomb, kagome, and herringbone lattice configurations. We present a full phase diagram for the case \\(m_2/m_1 = 2\\) and list a number of geometries that are found for higher integer mass ratios.

In recent years there has been growing attention on the risks posed by climate change. One relevant question for financial stability is to which extent the materialisation of transition risks emerging from the sudden implementation of climate change mitigation policies would impact the financial system. In this paper we analyze the effects of changes in carbon price on the European banking system. We assess this climate change transition risk through a banking sector contagion model where firms are negatively impacted by an increase in carbon prices. Using a unique granular dataset we evaluate the consequences of a combination of different increases in carbon prices and firm emission reduction strategies. We find that taking early policy action, implying more gradual changes in carbon prices, is not expected to lead to adverse impacts on the banking system, especially if firms reduce their emissions efficiently. Conversely, a disorderly, abrupt transition to a low carbon economy requiring very high sudden changes in carbon prices might have disruptive effects on the financial system, especially if firms fail to reduce their emissions.

We present an extension of the framework introduced in [1] to treat multicomponent systems, showing that new degrees of freedom are necessary in order to obtain the desired boundary conditions. We then apply this extended framework to the coupled Gross-Pitaevskii equations to investigate the ground states of two-component systems with equal masses thereby extending previous work in the lowest Landau limit [2] to arbitrary interactions within Gross-Pitaevskii theory. We show that away from the lowest-Landau level limit, the predominant vortex lattice consists of two interlaced triangular lattices. Finally, we derive a linear relation which accurately describes the phase boundaries in the strong interacting regimes.

Since the term was first coined in studies on the 1990s Japanese crisis, the concept of zombification has been investigated and revived repeatedly when concerns arise about credit misallocation and stagnating productivity growth in an economy. The starting point for these studies nearly always involves trying to identify the so-called ‘zombie’ firms. This has led in the past years to a proliferation of different definitions and identification methodologies. We survey the most prominent definitions, discussing advantages and limitations of each. We also undertake a comparison of methodologies on a common dataset for euro area firms from 2004-2019, with the exercise revealing limited overlap and low comparability in the firms identified by several prominent studies. In response, we introduce a formalisation of zombie-classifications which helps to make order in the growing number of variations and identification methodologies. Moreover, this formalisation also helps extending the concept of binary identification to that of fuzzy zombie-identification. In particular, we introduce a general procedure to turn arbitrary binary classifications into fuzzy ones showing it successfully increases consistency between zombie definitions.

Overlapping portfolios constitute a well-recognised source of risk, providing a channel for financial contagion induced by the market price impact of asset deleveraging. We introduce a novel method to assess the market price impact on a security-by-security basis from historical daily traded volumes and price returns. Systemic risk within the euro area financial system of banks and investment funds is then assessed by considering contagion between individual institutions’ portfolio holdings under a severe stress scenario. As a result, we show how the bias of more homogeneous estimation techniques, commonly employed for market impact, might lead to loss estimates that are more than twice as large as losses estimated with heterogeneous price impact parameters. Another new feature in this work is the application of a price-at-risk measure instead of the average market price impact to evaluate the tail risk of possible market price movements in scenarios of different severity. Our results also show that system-level losses at the tail can be three times higher than average losses using the same scenario. JEL Classification: G01, G12, G17, G23, G32
